Dermal Penetration Study Services

Dermal penetration studies provide the most relevant safety data for quantifying topical risk exposure via the skin. Our metabolism team has extensive experience with dermal penetration studies and delivers critical data to help gain regulatory approval and advance R&D programs for agrochemicals, cosmetics, pharmaceuticals and chemicals.

Studies are conducted with both radiolabelled and non-radiolabelled compounds. The use of a radiolabel typically facilitates more rapid analysis, assessment of mass balance and skin-fraction penetration. We can integrate radiolabelled dermal studies with 14C and 3H radiosynthesis of your test compound(s).
